Argument can be either positive or destructive. Argument for the sake of heaven seeks to find the truth about something important by debate. Argument for the sake of power tries to defeat the other in order to gain power or status. Korach, when he instigated rebellion against Moses was arguing for the sake of power. Moses and Aaron had leadership of the nation and the priesthood. Korach and his companions wanted that. So too in our relationships. Simply being correct about something is not sufficient reason to argue.
